Phil Caldwell became the CEO of Ceres Power in September 2013, following investment from IP Group. In June 2023, Ceres marked its move from the Alternative Investment Market to the Main Market of the London Stock Exchange.
The company issued an unexpected revenue warning in December 2023: contract negotiations were taking longer than expected. Further difficulties emerged in March 2025 when Bosch announced that it was withdrawing from a joint venture with the company.
